I'm new enough that I don't know either, (if I had to guess, it's treating a normal variable as an array, i.e  my $foo=1; print $foo[5]; will not work, I think (UPDATE: Having read the other posts, it looks like I'm wrong about that)). For future reference, please place your code between <'code'> <'/code'> in posts like these (minus the quotation marks though). It makes it much easier to read. Here's a cleaned up version of your code:

foreach $item (@results) {
@line=split/,/, $item; 
$seen{$line[1]}="0"; 
#$seen{$item}=0; 
#print "LINE 1 $line[1]\n"; 
} 
foreach $item (@results) { @line=split/,/, $item; 
if ($line[0] =~ /1|6|7|8|9|5/) { &integrate; sub integrate { %matching
+=(); 
if ($line[0]=~/6|7|8|/) { $overlapc=$line1; 
foreach $itemi (@eresults) { @linei=split/,/, $itemi;
if ($linei1 eq $line1) { @matchone=split/ /, $linei[2]; $lengthandn=$l
+ine[4].',', $line[5];

##error here--- Useless use of array element in void context--can u please tell me what this line does.

 $matching{$matchone[0]}="$lengthandn"; 
$matching{$matchone[1]}="$lengthandn"; 
#$seenclone{$matchclone[1]}="1"; #print "678 line 1 $line[1] Length $l
+engthandn matchclone $matchclone[1] m0 $matchclone[0]\n"; } }

It seems to be missing portions though. All the variables and arrays should be declared at the beginning of the script (as far as I know). One other thing, all of the locations where a number was placed in square brackets were converted to links, and the square brackets disappeared. This is because you did not place your code between the

 tags, so allways do that, please.
